Encode graph as text

Source: R/graph_as_text.R
graph_as_text.Rd

Encode a graph as 'graph6', 'sparse6' or 'digraph6' choosing the format automatically.

Usage

graph_as_text(object, ...)

# Default S3 method
graph_as_text(object, ...)

# S3 method for class 'list'
graph_as_text(object, ...)

Arguments

object

igraph/network object or a list thereof

...

other arguments, currently ignored

Value

A character vector of encoded graphs.

Details

If object is a list it may be a mixture of 'network' and 'igraph' objects.

Methods (by class)

  • graph_as_text(default): The default method chooses the encoding format automatically using choose_format().

  • graph_as_text(list): The list method applies the default method to each element.
